I have Oracle DB Table with one of its column (VARCHAR). I read and write to
this data [non-english or English] using VC application then everything
works fine. But if I use a VB application to read the data[non-english] and
write it back to the same palce the content is corrupted.
Any help is appreciated

The problem is solved. It was due to the difference in the way, the Unicode characters are handled by "Oracle Provider for OLE DB" (OraOLEDB.DLL) and "Microsoft OLE DB Provider for Oracle" (msdaora.dll).
Refer : http://support.microsoft.com/kb/q244661/
My vb application was using msdaora.dll while VC++ was using OraOledb.dll !

Noone here is just going to send you stuff. We'll help you with your code, but your responsible for actually putting effort into searching for your solution first.
BTW, there are no OCX controls that will give the you look and feel of Office controls. You actually have to code it. But like I said, Google for it first. There are TONS of examples out there.

Noone is going to look at this post, simply because of it's size. Don't post your entire app, just the relevent code.

Yes,thank you for the advice. I have post up the error founded. Do you know what might be the problem occurred?
|
|
|
|

The error already told you exactly what is going wrong: System.InvalidOperationException: The connection is already Open (state=Open).
Read a little below that and you will find the error is comming from the class System.Data.SqlClient.SqlConnection with function Open(). So it looks to me you're trying to open a connect to a database when there already is an open connection.

Oh,thank you so much for helping me to solve this problem. I'm quite new to VB.Net,but feel so lucky U manage to help me. I solve this problem by rechecking all the connection open between my database and this Engine. Thank you so much Mr Gerben Jongerius.
Wish You and the others Have A Wonderful New Year~!

The rule for database connections is simple. Open the connection to the database as late as possible, execute your batch as quick as possible, then close your connection as early as possible. It's very bad practice to hold open a database connection for the life of your app.

I have an aspx page that generates an xml file and saves it to a directory using server.mappath. I want to use this page to generate that xml file when someone logs in. How can I reference this to make it happen?
E

|

|
|
Hadware,
use session or cookies to trace the login of users and then redirect to that XML page
something like this ...>
Session("strEmail") = Request.QueryString("ID")
Response.Redirect "xmlPage.aspx"
Session will be available on that page too and u can use this session to print some data according to it in XML format.
Hope it is helpful for you

Any thoughts on why changing a form's ShowInTaskbar property at runtime would cause an "Error Creating Window Handle" error?
Thanks ... George

how do you open a web page in the default web browser using vb.net
http://ixpress.sourceforge.net/feedmonster

System.Diagnostics.Process.Start(WebURL)
... where WebURL is a string containing the URL of a web site

If you want to test if the URL is reachable (e.g. an Internet connection is available and the URL is valid), pass the URL string to this function.
Private Function WebSiteIsAvailable(ByVal linkText As String) As Boolean
Dim URL_Object As New System.Uri(linkText)
Dim URL_WebRequest As System.Net.WebRequest
Dim URL_WebResponse As System.Net.WebResponse
Dim Response_Result As Boolean
' Attempt to get a response from the URL
Try
URL_WebRequest = System.Net.WebRequest.Create(URL_Object)
URL_WebResponse = URL_WebRequest.GetResponse
Response_Result = True
Catch Any_Error As Exception
Response_Result = False
End Try
URL_WebResponse = Nothing
URL_WebRequest = Nothing
URL_Object = Nothing
' Return the result
Return Response_Result
End Function
